To all 'wi'mm may concern;

Be it known that l Bonner ll JlIEHLE, a citizen of the United States, and resident of Chicago, in the county of Cool: and State of Illinois, have inventede certain new and use f ll lniprovementin Bed-Motions for Printing-Presses, of which the following is a specification.

The invention relates to that close of ms chines in which a heavy bed or body is reciprocated, as in printing presses in which the form is carried upon a bed having a reciprocating increment under the impression cylinder and employinggates to form slots which engage with a crank to stop and reverse the movement of the type bed.

; An object'of the invention is to provide positive acting means which are free from times.

springs for operating the gates, and. for holding the some in proper position at all A further object of the invention is to po sition the operating mechanism for the gates relative to the bed, so that is large crank stud roller nioy be used without increasing the normal height of the bed.

These and other objects will in part be obvious, and will in part be hereinafter more fully described.

in the drawings, which. show by way of Figure 1 is arear side View of a portion 01 a printing press in elevation, embodying my improvements; Fig. 2 is a rear end View of the same; Fig. 3 is a sectional plan view showing in detail the construction of the gate mechanism for mtarding, stopping and accelerating the movement of the type bed; Fig. is a similar View of the gate at one end of the bed closed and in dotted lines the gate opened; and Fig. is a similar view of the gate at the other end of the bed.

In the preferred embodiment as shown, the bed 2 is of the usualflat bed reciprocating type. Fixedly secured to the under side of the bed 2 is e raclr frame 1, which is provided with upper and lower racks 3 and 4' with which the driving gear 5 'alternntely engages. A reversing crank 84. 1s fixed to the said gear and is provided with a large fric-v tion roller The diving gear 5 is secured to the bed motion shaft 6, which extends outside the typc': bed or press frame, and receives motion from any suitable drive gear, which it is not necessary to describe and lower racks 3 and 1) by means or the bed motion rocker frame 20, which con sists of'the fulcrum extensions 16 and 17, which have bearing in the standard 18 and the side frame a bearing 20 (formed on the main body 20) in which is j ournalcd the bed motion shaft 6; an arm 21 (extending from the main body 20 and the bearing 20) which has a stud and friction roller in the cam groove 23 of the bed motion cam 24- on the cam shaft 25. The shaft reccivcs motion in the usual way from a regu ler train of gears, which it is unnecessary to show in order to understand the present improvement. Atv one end of the rock frame 1 hinged a gate :28. Said gate is hinged to upper and lower lugs a by studs Z). The gate is formed with an arm 29 which carries a roller 30. Said gate is also provided with 2. lug which carries a roller 32. These rollers are positioned to cooperate with face cams 31 and 33 respectively, which cams are mounted on brackets r-of the framework of the press. Likewise the gate 28" at the other end of the bed ishinged to upper and lower lugs o by studs 6. This gate 28 has an arm 29- carrying a roller 30. A roller 32' is mounted directly on the gate 28'. These rollers 30 and 82 cooperate with similar face cams 31 and 33 carried by the brackets 1'. As the bed is reciprocatcd, the gates 28 and 28- will be oscillated on their supporting lugs. It will be noted that the came 31, 31, and 33 all face in the same direction, and are locatedalong one side of the gates, thus giving the entire space below the bed for the height of the gates and the opening cams extend the full length of movement of the gates, so that the gates are constantly. under positive-control. I

The working fces 39 and 39'of the gates 28 and 28', together with the shoulders 40 and 40 of the rack frame '1, form the usual slots in which the crank stud roller 35, on reversing crank 34:, operates to retard, stop and reverse the movement of the type bed,

in the following manner: Beginning. at the position shown in Figs. 1 and 3, in Whiclrthc type bed is at stop at the end of the printing stroke, the driving gear 5 being disengaged from both racks 3 and 4, and the movement oi the type hed being controlled hy the crank stud roller 35 in the slot formed by the shoulder .1-0 of? the :ack frame I and the. working taco 39 ot the gate 2*. Hotel'- ring to l i 3 the roller 32 again t the an: 33 is holding" the ate 98 in its t'lmml pod tion, the roller 30 against the cam ill preventing the working; face il ol the gate trout swinging); in too close to the rack l'rnnae 1.. A5. driving gear 5 rotates in the direction indicated by the arrow. the type llttl J and the rack frame i see Fig: t, moving to the right on the non-printing stroke. the roller :32 passes over the portion o of the and therollor passes over the pot:-

t i l l l t ("21311 on on tion (I of the cam 31., thus positively openthe gate and releasing the said crank stud roller 35. [it the same time, the crank stud roller 555 i so released, the driving gear 5 which has hccn lowered by the movement of the bed motion rocker frame engages lower rack 4- and drives the type bed on the non-printing stroke. The roller acting against the portion a of the cam 31, serves to positively hold the gate 28 open, as shown in dotted construction in Fig. 4-. The set screw .2 abutting against'the gate frame 98, limits the n'iovomcnt; of the said gate and prevents the roller 30 from leaving the guide surface 2.

Near the cud of the noirprinting stroke, as shown in Fig. 5, the roller 32' over the portion j of the cam and the roller 30, passes over the portion g of the cam 31, thus positively closing gate 28', as shown in dot ted constructiongin .7. The closing of the fnlfi engages the crank stud roller 35, on reversing crank. Mi in the slot. formed. by the working surface 39, and theshonldcr 4.0 of the rack frame 1. At. the same time. the. said crank stud roller is so engaged,' the driving gear is raised by the naive merit. of the bed motion rocker frame 20. thus being disengaged from lower rack -l-. The movement of the type bed now controlled by the crank stud roller 33 in the slot formed as above, and comes to a t'nll stop at the end of the non-printing stroke. [is iilriring gear 5 continues to rotate, and the type bed and rack "Frame move to the left on the printing stroke, the roller 32 passes over the portion of the cam $3 and roller 3Ov passes over the portion 9 ot' the cam 31, thus positively openii'ig the gate 23' and releasing the said crank stud roller 35. At the same time the crank stud roller 35 is so released the driving gear 5 which has been raised by the movement of the bed motion rocker frame 20, engages with upper rack 3 and drives the type bed on the printing stroke. The roller 30 act in; against. the portion h of the rain Bl, serves to positively hold the gate 28' open,

as shown in 3 and 'lhe set screw a buttin a amstthc mte frame 2:5 hnntstue l nun enn-nt oi the said gate, and prevents the rollers 3t from leaving the guide surface It. hear the 0nd of the 'Jrintin; stroke, the roller 32 passes over the portion of the cam 33 and roller 0 pa" over the portion r! of cam 31, thus po cly closing the gate 28. as shown in Figs. 3 and 4t, and engaging the crank stud roller 35 in the slot: formed hy the working surface 39 of the gate 98, and the shoulder it) of the rack :trame 1.. At. the same time, the rank stud roller 35 is so engaged, the driving gear 5 is lowered by the movement of the bed motion rocker frame 20, and thus disengaged from upper rack 3. The typebcd is now controlled by the crank stud roller 35 in the slot. formed as ahcve, and comes to a full stopin the position shown in Figs. 1. and t I It will be'noted that the rollers for operatinp; the gates are located on opposite sides of the axis of each gate relative to their direction of movement, and consequently impart a positive opening and closing more meat, to the gate-.- The opening cams also extend the full length of movement. of the gates, and, therefore, continue to hold the gates open.

The herein improved mechanism aroids the necessity of placing the cams below the line of the crank stud roller, thereby saving room in the height of the press when a large crank stud roller is employed. Itwiil also be readily seen that this improved mechanism notonly gives an effective method for operating the gates but one that causes less wear on the parts, is easily adjusted to take up any play due to wear, and, furthermore. one which eliminates'the use of springs which formerly were necessary in order to have a strong tension to keep the gates in their proper position atthe ends of the stroke when running at. high speed, this excessive spring pressln'e making hard work on the cams, also producing a side strain on the'rack "frame. which had a. tendency to work the type bed out of its true workingline. By the simple adjustment of the set screws 8 and a, the rollers 30 and 30' may ltl kept; against the guiding portions (2 and 1 of the cams 3t and 31', thus taking up anyplay due to wear. The cams, too, are easily adjustable independently of each-other, it there he need to put them in alinemcnt. or to take up any play due to wear. This can he done by inserting packing between the brackets r and the cams. I

It will he ohwious that minor changes in the details of cmtshruction and the arrangement of the parts may he made without itparting from the spirit; of my invention.
